Q

Can you tell me a bit about four common types of foundations?

A
  1. Trench/ strip footings. Generally used in residential dwellings for closely spaced walls/ columns
  2. Raft. Slab foundation over the whole site, spreads load for lightweight structures. Eg for a conservatory or a workshop.
  3. Piled. Long and slender, reinforced steel columns into the ground to deeper strata for poorer soil conditions and high loads.
  4. Pad. Slab foundation under individual or groups of columns so column load is spread evenly, used for large purpose-built structures such as warehouses.

Q

What is ‘efflorescence’?

A

White marks caused by hydroscopic salts in brickwork

Formed when water reacts with natural salts in bricks and mortar

Water evaporates on outer surface of wall depositing salts

Q

What are the ‘Institutional Specifications’ for offices?

A

Most new offices constructed of steel/ concrete frame

Steel frame offices usually have larger span floor plans and less columns

Concrete frame offices usually have more columns, lower floor heights and a shorter span between columns

Check architect’s plans or building manual if you cannot determine construction type on site

Q

Can you tell me about some types of air conditioning systems?

A

VAV - variable air volume (highest capital cost but most flexible)

Fan coil - usually 4 pipe (lowest capital cost and good flexibility, but higher running cost)

VRV - variable refrigerant volume (lower capital costs but higher running and maintenance costs)

17
Q

What are the different types of fit out?

A

Shell and core - common parts completed but office areas are shell for occupier fit out

Category A - such as grade A specification

Category B - complete fit out to occupier’s specific requirements, such as cellular office spaces and enhanced finishes, etc

Grade A - brand new building with high spec, excellent benefits of location

Grade B - no longer new, may be out of city centre

Grade C - poorer quality, usually 20 years older or more

18
Q

Current institutional specification for industrial/ warehouse space

A

Minimum 8m clear eaves with 10% roof lights

Plastic coated steel profiled cladding with brick or blockwork walls to approximately 2m

Full height loading doors

3 phase electricity power

18
Q

Current institutional specification for industrial/ warehouse space

A

19
Q

What are some types of building defect?

A

Inherent defect - defect in design or material which has always been present

Latent defect - fault to the property that could not be discovered by a reasonably thorough inspection of the property

20
Q

What four steps should you follow if you identify a defect?

A
  1. Take photographs
  2. Try to establish cause
  3. Inform client of your investigations
  4. Recommend specialist advice from building surveyor or structural engineer
21
Q

What are three common causes of defects?

A

Movement

Damp

Condensation

22
Q

Tell me more about ‘movement’

A

Subsidence - downward movement of building foundation caused by loss of support of soil/ change in soil conditions

Heave - expansion of ground beneath part or all of building. Could be caused by tree removal and subsequent moisture build up in soil

Horizontal cracking in brickwork - could be due to cavity wall tie failures

Shrinkage cracks - often in form in new plasterwork during drying out

Other cracks - may be caused by differential movement such as settlement cracks

Thermal expansion / movement can also cause cracks

23
Q

Tell me more about ‘damp’

A

Wet rot - caused by damp and timber decay. Signs include musty smell, wet and soft timbers, visible fungal growth, high damp meter

Dry rot - caused by fungal attack. Signs include fungal spores (fine, fluffy white strands and large orange mushroom-like bodies), strong smell, cracking paintwork, crumbing timber

Rising damp - usually up to 1.5 metres above ground level

Condensation - can be caused by lack of ventilation, and background heating. Signs include mould and condensation on windows/ walls

24
Q

What are some common building defects in ‘Period’ buildings?

A

Dry rot

Wet rot

Tile slippage

Death watch beetle

Damp penetration (roof and ground)

Water ingress (windows and door openings)

Structural movement/ settlement

25
Q

What are some common building defects in ‘Modern Industrial’ buildings?

A

Roof leaks around roof lights

Damaged cladding

Cut edge corrosion

Blocked valley gutters

Water damage from poor gutters or burst pipes

Settlement/ cracking in brickwork

26
Q

What are some common building defects in ‘Modern Office’ buildings?

A

29
Q

What are the three typical phases of investigation?

A

Phase 1 - review site history with desk top study and site inspection - use property observation checklist

Phase 2 - investigation to identify nature and extent of contamination with soil samples taken (bore holes)

Phase 3 - remediation report setting out options with design requirements and monitoring standards

30
Q

What should you do if you have contamination concerns?

A

Suggest a specialist report?

Do not provide valuation advice until report is commissioned

Caveat advice provided with appropriate disclaimer / special assumption

Deduct remediation costs from gross site value

31
Q
